Christina Aguilera showed off her slim figure in a bra and skirt on the set of an upcoming new music video on Wednesday.

Aguilera donned a black bra and bodycon mini-skirt, showing off the weight loss she first debuted back in March, on the set of her music video for "Hoy Tengo Ganas De Ti" -- a track she collaborated on with Alejandro Fernandez. With red lipstick and platinum curls, the 32-year-old resembled a pin-up beauty from yesteryear.

She tweeted a photo of her slimmer figure, against an ocean backdrop, for fans.

The singer has previously had to defend her curvy figure from critics who lambasted her in the press for gaining weight. In October, Aguilera said she embraces her body and the changes that have happened over the years -- through motherhood, her 30s and more.

"I've always been one to make it very clear, love me or hate me, take it or leave it, this is who I am," she told People magazine. "I embrace my body, and I embrace everything about myself. Coming full circle is a celebration of freedom and happiness because that's what [my new album] Lotus is representing. I'm embracing everything that I've grown to be and learned to be."

This week, it was reported that Aguilera will return to "The Voice" for Season 5, taking her spot back from Shakira, who replaced the "Your Body" singer while she focused on her own music and the promotion of "Lotus." She reportedly inked a deal worth $17 million.
